2. Introduction
1.What is a RFID system?
Hardware requirements
1. ATMEGA 328p Microcontroller
2. EM-18 Module (RFID Reader)
3. Passive tags
4. RTC (Real Time Clock)
5. PCB
6. LCD(16*2)

3. List of software and tools used
1. ARDUINO IDE
2. EXPRESS PCB
3. ARDUINO UNO

4.  RFID stands for Radio Frequency Identification.
 RFID is a technology which wirelessly identifies the
chip or tag of interest and captures the data.
 It is a member of AIDC(Automatic Identification and
Data) technologies.
 RFID system comprises of
1. RFID tags
2. RFID reader
3. RFID middleware.

5.  RFID tags contain a wire circuit and antenna for
data transmission.
1. Active 2. Passive

6.  RFID readers are devices
which emits radio signals
through antennae.
 They also provide the
necessary amount of power
to the tags, if passive tags a
 RFID readers get the collect
the data stream provided
by the tags. re used.

7.  It collects all the data that tags give, does the
filtering task.
 RFID middleware actually is used to control
and manage the RFID readers’ infrastructures.
 It is considered as the brain of any
 RFID system as it provides the most important
functionalities.
 Some of its key functionalities are efficient
management of data created by the RFID
system.

8. 1. ATMEGA 328P Microcontroller
 28-pin AVR Microcontroller
 Flash Program Memory: 32 kbytes
 EEPROM Data Memory: 1 kbytes
 SRAM Data Memory: 2 kbytes
 I/O Pins: 23
 A/D Converter: 10-bit Six Channel
 RTC: Yes with Separate Oscillator

10.  Operation voltage
5V DC
 Current of operation
is less than50mA
 Frequency of
operation: 125 KHz
 Distance of operation
10cm

11.  This tiny RTC module
is based on the clock
chip DS1307 which
supports the I2C
protocol.
 It uses a Lithium cell
battery (CR1225).

12.  We used a 16*2 LCD
means 16 columns
and two rows.
 It has 14 pins.

16. Tag is detected and entry registered

17. Same tag detected again and exit
registered
